For anyone not interested in re-upping a contract and getting the new iPhone, it is still a good time to check your plan. I have four iPhone 6's on one plan with Verizon, think it was the "More Everything" plan. Was running $260 per month for 10GB's of shared data. Pretty effin expensive but there isn't much choice if you want Verizon. That broke down to $80 for the data, $40 per phone for line access and then the various fees and such.
Verizon has a new plan now that actually works nicely if you are the type to hold on to a phone for a while. If you are past your last contract that got you a subsidized phone, it works out. The new plan is $80 for 12GB of data, but if your phone is off contract, the line access drops from $40 per phone to $20 per phone per month, instant savings of $80 per month and you get more data. They also include rollover now and "Safety Mode" so if you do go over your data it just slows you down rather than automatically purchasing more for $15.
I couldn't hardly believe Verizon was willing to offer a plan that actually reduced costs, but I switched and it seemed to work out, I went from $260 per month to $160 per month. Worth a look if you are out of contract.
